In the field of nanotechnology and nanoscience, transition metal oxides based nanocomposites (TMONCs) are promising for various application uses such as Supercapacitors, Sensors, Bactericidal properties, Photocatalytic Degradation, Solar Cells etc. Modification of transition metal oxide nanoparticles (TMONPs) to TMONCs by doping/mixing of another transition metal and metal oxide, carbon based nanoparticles, conducting polymers etc. to achieve enhanced surface area, increasing surface activities or number of active surface sites, reducing electron-hole recombination, increasing charge transfer processes etc. have been reported in literature. These improved properties are the possible reason for the enhancement in its practical applications efficiencies. This review summarizes recent development on transition metal oxides based nanocomposites for different potential applications. Also synthesis methods of transition metal oxide based nanocomposites have obtained an increasing attractions to achieve cost effectiveness and environment friendly routes of synthesis with high rate of production, high yield of product and also less toxic waste production. Transition metal oxides nanocomposites have been fabricated by various methods such as Microwave assisted synthesis technique, Sol-Gel method, Biosynthesis method, Co-precipitation process, Simple Chemical method etc. Different morphologies of transition metal oxides based nanocomposites have been summarized in this review article. Herein, this paper discuss about several reported synthesis techniques, various characterization techniques used for structural and surface properties identifications, different morphologies and various potential applications of transition metal oxide based nanocomposites.

Zn 1−x Cu x Al 2 O 4 nanoparticles were prepared by microwave combustion technique with metal nitrates as precursor materials. Powder x-ray diffraction studies confirm the formation of single phase of spinel pure and copper doped zinc aluminates. HR-SEM images reveal the agglomerated coalescence morphology with pores. Elemental analysis (EDX) confirm the presence of Zn, Cu, Fe and O. UV-Visible Diffuse reflectance spectroscopy is used to find the optical bandgap and it is found to decreases from 5.45 eV to 3.57 eV. IR spectra show three major peaks which confirm the phase formation of Zn 1−x Cu x Al 2 O 4 nano aluminates with spinel structure. Vibrating sample magnetometer (VSM) measurements reveal the super paramagnetic nature of pure and copper doped zinc alumintes. The obtain results are confirmed that present pure and copper doped ZnAl 2 O 4 particles at nanoscale are to be potential candidate for catalytic, sensor and optoelectronic device applications.

“…CdS nanostructure thin film was synthesized by various methods and techniques such as chemical bath deposition method (CBD) [5], spray pyrolysis technique [1,10], thermal evaporation [10], chemical precipitation method [11], successive ionic layer adsorption and reaction method (SILAR) [12], doctor-blade technique [13], solvothermal method [14,15] and hydrothermal method [16,17]. Most of these methods and techniques require a high preparation temperature or annealing process, by using these methods the micro-cracks defects could be formed because of the thermal expansion coefficient mismatching between the film and the substrate [18,19]. Among these methods, simple and one step, low coast, high quality, high purity, very high crystallinity, and low-temperature method, the hydrothermal method was selected to preparative chalcogenide dS thin films [18][19][20].…”
